Admiralty Vector Chart Service

Overview

The Admiralty Vector Chart Service (AVCS) brings together Electronic Navigational Charts (ENCs) from national Hydrographic offices around the world and new ENC coverage produced by UKHO in co-operation with Foreign Governments to provide comprehensive, official, worldwide coverage.


Compliant

AVCS contains only ENC data that meets SOLAS Carriage Requirements for use within Electronic Chart Display and Information Systems (ECDIS).


Quality

AVCS meets customer requirements for a comprehensive, world-wide, full carriage compliant electronic chart service. AVCS continues to develop in response to customer feedback through an ongoing programme of enhancements. Full details of planned enhancements are available on the 'Future Enhancements' tab.


UKHO has instituted a programme of assessment by its professional cartographers where the content of the ENC is compared to relevant national paper charts. Any navigationally significant discrepancies identified are then investigated and resolved with the producing nation. No other electronic chart service offers this level of reassurance.

Carriage Compliant

The Admiralty Vector Chart Service only contains ENC data that meets Safety of Life at Sea (SOLAS) Carriage Requirements for use within Electronic Chart Display and Information Systems (ECDIS).

ENCs

Electronic Navigational Charts (ENCs) are digital vector charts produced to the International Hydrographic Organization's (IHO's) standards (S57 Version 3.1 and ENC Product Specification). They are referred to World Geodetic System 1984 Datum (WGS84) and are regularly updated with official update information distributed digitally.

Hydrographic offices do not take any responsibility for the accuracy or reliability of privately produced, unofficial charts.

Purchasing

AVCS provides cost-effective coverage of the world's major shipping routes, avoiding the need to purchase unnecessary data. AVCS is sold in two different formats, Folios & Units, offering the ultimate in purchase flexibility.


Folios

AVCS is sold in a series of Folios, which are geographic collections of ENCs selected for a specific purpose (e.g. transiting an area). They are designed to make ordering, maintenance and licensing as easy and flexible as possible. Each Folio is automatically maintained for any relevant changes to ENC coverage.


Transit Folios

These are designed to provide all the coverage needed for a vessel to pass safely through a region when not engaging in local trade, saving you the expense of purchasing detailed coverage for regions that you are just passing through, whilst including more coverage to negotiate the choke points such as the Suez Canal and Malacca Straits.


Regional Folios

These cover a much smaller geographical area than Transit Folios and include all Coastal and some Approach ENCs, where coastal coverage is not available. Regional Folios are designed for local and coastal trade, where more detailed coverage of complex coastal waters is required. They do not include Port Approaches or Entry.


Port Folios

These typically comprise Approach, Harbor and Berthing cells grouped together into a single sales unit. Under typical operational conditions, vessels approaching a port directly from an ocean passage will require only Transit and Port Folios if not engaging in coastal operation.


Where a number of major ports are grouped in a complex waterway (e.g. Japan's 'Bungo Suido and Western Inland Sea'), a single Port Folio may provide coverage for all the ports in the area.

Chart by Chart

Hand-pick individual ENC chart coverage that meets the specific requirements of your Fleet to ensure precise coverage of your shipping routes.


All ENCs in AVCS can be selected on a chart-by-chart basis as ENC Units. These Units are the smallest unit of sale allowed by ENC producers and usually contain ENC data approximately equivalent to a paper chart.


Combination

Combine AVCS Folios of your choice with individual ENC charts for unrivalled coverage and voyage flexibility.

Licensing & Updating

Licensing

AVCS licences are for a 12 month period, within which you will hold an AVCS media pack, containing world-wide AVCS data, receive weekly updates to the AVCS data set and have access to online updates through the Admiralty Updating Service. Within the licence period, AVCS Folios and ENC Units can be added for periods of three, six, nine or twelve months, where data supply agreements allow. This offers maximum choice and the flexibility to match your chart holdings to your operational patterns.


Updating

AVCS includes remote updating software, the Admiralty Updating Service, free of charge. The software can be used to obtain immediate updates to your ENC data, either directly over the Internet or by email, anywhere in the world, at anytime. The service also allows the mariner to actively manage their data holdings with the download of voyage-specific updates, minimising transmission costs for vessels at sea.


An information log is automatically maintained for the Officer of the Watch to ensure continuity during crew changes. All updates are hosted on a secure server and are encrypted and digitally signed to ensure that they are authentic and uncorrupted when you receive them.


Updates to ENC data within AVCS are also supplied weekly on CD as standard, ensuring that every AVCS customer has a complete and up to date set of data on board, with the option to easily access additional data if required.


The Admiralty Digital Catalogue is included free of charge within AVCS.

Pricing

Fixed Annual Cost

With AVCS Folios you can be sure of maintaining access to all the latest information without the need to repeatedly amend your budgets. Any new ENC data that becomes available will be included in the appropriate AVCS Folio at no additional cost for the period of your Licence.


Complete Flexibility

Every AVCS customer is provided with a complete set of Base discs containing every ENC available within the Service. These discs are 'locked' but allow your vessel to carry complete coverage whilst only paying for the folios and charts required. Chart holdings can be upgraded quickly and easily at any point during the licence period, unlocking additional charts to extend your coverage.


Support

The Admiralty Vector Chart Service is backed by UKHO Helpdesk support during normal office hours, and an emergency permit generation helpline outside those hours, providing complete confidence and peace of mind.

Emergency Chart Permits

In certain circumstances it may be necessary for a vessel to get access to an AVCS chart at very short notice, for instance if she has to divert her route due to a medical or safety emergency. In these emergency circumstances, individual AVCS Chart Permits can be obtained from the UKHO 24 hours a day, 365 days a year. These Chart Permits can be transmitted direct to the vessel by email wherever possible, by fax, or simply by reading the characters out over the telephone or radio. Each Chart Permit consists of 64 characters.

To obtain an AVCS emergency chart permit please contact the UKHO Helpdesk during UK normal office hours. Outside of office hours please contact the UKHO Watch Keeper by emailing navwarnings@btconnect.com, phoning +44 (0) 1823 353448 or faxing +44 (0) 1823 322352. Please quote name and contact details, the vessel name, the User Permit Number of your ECDIS system and the cell number(s) required.

New Features

In response to feedback from customers, the UKHO is continuing to develop AVCS.


New AVCS Features

Chart-by-Chart Ordering
  • All ENCs in AVCS are available to be selected on a chart-by-chart basis as ENC Units. These Units are the smallest unit of sale allowed by the ENC producers and usually contain ENC data approximately equivalent to a paper chart.

  • AVCS also continues to be available in Transit, Regional and Port Folios, offering customers the maximum flexibility to choose between managed folios and chart-by-chart selection of the coverage that they require.
Flexible Licensing of Units
  • The existing flexible licensing of AVCS Folios is extended to ENC Units. Therefore it is possible to add individual ENC Units to an AVCS licence for periods of 3, 6 and 9 months, where permissions allow.
AVCS Certificate of Ownership
  • All AVCS customers receive an AVCS certificate of ownership confirming that the licensed vessel is navigating on AVCS and that AVCS is comprised only of SOLAS carriage compliant ENCs.
Admiralty Digital Catalogue
  • A new version of the Admiralty Digital Catalogue is available to support AVCS. The new Catalogue includes:

    • Improved selection of AVCS products, allowing easy combination of coverage selection by both AVCS Folios and ENC Units.
    • A new T&P NMs tab allowing geographical and route-based searching of all Admiralty T&P NMs. This gives all Admiralty customers, including AVCS customers, access to the latest T&P NM information, updated weekly. This will help to ensure that route planning decisions are made based on the most complete information available.
